With all the hot weather this summer, 2012 has had 13 ozone action days so far – already more than last year’s nine days, seven in 2010 and six in 2009. Breathing ozone can trigger coughing, a scratchy throat, or worse, it can aggravate asthma and emphysema.
Tomorrow’s predicted heat could cause problems for certain groups of people and as a result, state environmental officials have called for an air quality action day for the Pittsburgh area.
The Department of Environmental Protection declared a code orange Air Quality Action day for Wednesday in the Pittsburgh area. This includes Allegheny, Armstrong, Beaver, Butler, Fayette, Washington and Westmoreland Counties.
